TV This Week: Jan. 27 - Feb 2: '30 Rock'

You go, "Good Wife": The lovely and talented Julianna Margulies will have the chance to add to her record number of SAG trophies — she's got eight already, mostly from her stint on "ER" — at the "19th Annual Screen Actors Guild Awards." (TNT, 5 p.m.)

Last time we saw a giant squid, it was engaged in a life-or-death struggle with Capt. Nemo's Nautilus in the 1954 Disney flick "20,000 Leagues Under the Sea." But that one was fake. Not so the super-sized cephalopod caught on camera in the special "Monster Squid: The Giant Is Real." (Discovery, 8 and 11 p.m.)

MONDAY

TV legend Larry Hagman is gone. But his villainous Texas oilman, J.R. Ewing, lives on, for a little while longer, when the rebooted "Dallas" returns for a new season set to include the handful of episodes that the actor, above, filmed before his passing in November. (TNT, 9 and 10:03 p.m.)

TUESDAY

With his assembly-line innovations that made the automobile affordable for nearly all, perhaps no one person did more to shape our nation and its culture than Henry Ford. The iconic industrialist is profiled on a new "American Experience." (KOCE, 9 p.m.)

WEDNESDAY

"Who Killed Lindbergh's Baby?" Out of all of the previous century's "crimes of the century," it remains one of the biggest mysteries. Present-day forensics and behavioral-science experts reopen the case on a new edition of "Nova." (KOCE, 9 p.m.)

Keri Russell and Matthew Rhys are "The Americans" — or are they? No, they are in fact KGB agents from the now-defunct Soviet Union, posing as solid U.S. citizens while running a network of spies in Washington, D.C., in this 1980s-set drama. (FX, 10 p.m.)

THURSDAY

"What the what?!" "I want to go to there." "Blerg!" Who will supply us with catchphrases now that Tina Fey, below, and her Emmy-winning showbiz satire "30 Rock" are signing off after seven screwball seasons? "Blerg," indeed. (NBC, 8 p.m.)

FRIDAY

It's have banjo, will travel, when the new rock-doc "Mumford & Sons: The Road to Red Rocks" details the chart-topping British folk group's preparations for its performance at the famed Colorado venue. (Showtime, 8 p.m.)
